interfaces is poorly understood. Bed- form generation and impacts on bed 

 shear stress (hence on intrusion distance) are poorly understood. 



Sedimentation within estuaries will impact salinity intrusion. We 

 need better understanding of how sediment supply and transport will vary 

 with global climate change. 



SECT. 10. SEDIMENTARY PROCESSES IN THE ESTUARINE REGION 



We need to review impacts of global climate change of precipitation, 

 surface runoff, and sediment supply to estuaries. 



We must improve our understanding of changes in tidal asymmetries 

 (nonlinear dynamics) in estuaries. These asymmetries will impact not only 

 tidal range, but sedimentation patterns, trapping efficiencies, etc. This 

 is a critical requirement for understanding estuarine sedimentation. 



We need improved understanding of near-bed and suspended- load sediment 

 dynamics: basic physics.
